When to use Protect PDF
This tool is useful when the main problem matches its name exactly. If your issue is page order, use an organize workflow. If your issue is file size, use an optimization workflow. If your issue is privacy or access control, use a secure workflow. DocNimble tries to keep these distinctions clear so visitors do not waste time clicking through unrelated PDF tools.
Current limitation
This tool passed real engine checks and has an implemented end-to-end runner in the current batch. Password protection uses the provided open password.

Privacy note
Files run through the private workspace rather than directly from the public page. Completed outputs are exposed through tokenized downloads, and the privacy page explains retention in plain language without making impossible claims.

Why this page exists even before every tool is live
Tool pages help visitors discover the right workflow, understand limitations, and decide whether the current build already supports their task. That is useful for search, for user trust, and for future expansion, provided the page never hides the real execution state.
